John,

I think you'll need to get in touch with Samuel Aguilera, Shorten2Ping's author, for an answer to that.

I'm bummed ping.fm cut him off like that. I've been a fan of ping.fm for quite a while and loved the integration Samuel provided with Shorten2Ping.

I'm sorry your configuration isn't working. I really am. If I could go back to Shorten2Ping tomorrow, I'd do it.

Dlvr.it is nice. One of the things I like is its use of RSS. I wish I could add more than Twitter and Facebook posting, but that's pretty minor. As far as I know there is no plugin for WordPress.
